Definitions
- the invention relates to a method and a control unit for carrying out a spin program for a cleaning device and a cleaning device.
- EP 2 309048 A1 describes a drum for a washing machine with at least one driver rib.
- the approach presented here has the task of creating an improved method and an improved control unit for carrying out a spin program for a cleaning device as well as an improved cleaning device.
- a method for carrying out a spin program for a cleaning device with a rotatable, ribless drum for receiving the textiles includes a step of providing a first movement signal to an interface to a drive of the cleaning device, the first movement signal causing the drum to rotate in a first direction until the drum has reached a first setpoint speed.
- the method further comprises a step of providing a second movement signal to the interface to the drive.
- the second movement signal represents a second rotational movement of the drum in a second direction opposite to the first direction until the drum has reached a second target speed that is greater than the first target speed.
- the method also includes a step of further providing a further first movement signal to the interface to the drive of the cleaning device, the further first movement signal causing a further first rotational movement of the drum in the first direction until the drum has reached a further first setpoint speed, which is greater than the second target speed of the previous second rotary movement.
- a further second movement signal is provided to the interface to the drive, the further second movement signal representing a further second rotary movement of the drum in the second direction until the drum has reached a further second target speed that is greater than the further first target speed the previous further first rotary movement.
- at least one of the steps of further providing is repeated until the further first setpoint speed or the further second setpoint speed reaches a predetermined maximum speed.
- the method also includes a step of providing a third movement signal to the interface to the drive, the third movement signal representing a third rotational movement of the drum at the predetermined maximum speed in the direction of the previous step of further providing.
- the method can, for example, be carried out or controlled in a washing machine, such as can be used, for example, for private, but also for commercial purposes.
- the cleaning device can preferably be used to clean textiles so that they run through a spinning program, for example.
- the drum can, for example, also be referred to as a laundry drum and is shaped in order to clean the textiles inside.
- an inside of a drum shell of the drum is advantageously made or can be made smooth with the exception of a plurality of knobs.
- a drum without ribs can be used if the drum does not contain any geometry protruding from the surface where the drum radius is reduced by more than 10%.
- No ribs can mean that the drum does not have a rib on the inside which extends between the drum base and the drum opening, for example parallel to the axis of rotation of the drum.
- a nub can be understood as a hump-like elevation on the inside of the drum.
- a nub can be shaped like a pyramid or a cone.
- a knob can have a circle or a regular polygon as its base.
- a nub can also be referred to as a structural element, bulge or mini driver.
- the drive can be implemented, for example, as a motor which, for example, can set the drum in motion, for example in the first direction.
- the first direction of the first rotational movement of the drum and, for example, the further first rotational movement of the drum can, for example, correspond to the clockwise direction or, alternatively, to a counterclockwise direction.
- the second direction of the second rotational movement of the drum and the further second rotational movement can correspond to the counterclockwise direction or, alternatively, to the clockwise direction.
- the second rotary movement is advantageously greater than the first rotary movement
- the further first rotary movement is greater than the second rotary movement
- the further second rotary movement is greater than the further first rotary movement.
- the drum can advantageously be set in a pendulum rhythm so that the textiles advantageously rests against a drum shell of the drum in the rib-less drum.
- the third movement signal advantageously causes at least one complete revolution of the drum in order, for example, to spin the textiles in the spin program.
- the method can comprise a step of calculating the maximum speed using a predetermined g-factor, a drum radius value which represents a drum radius of the drum, and the gravitational constant.
- the g-factor can advantageously be in a range between 2 and 6, with it advantageously being 4.
- the second movement signal, the further first movement signal and the further second movement signal can be provided for a predetermined period of time, the predetermined period of time corresponding to half a period of a pendulum frequency. In this way, a back and forth oscillation can be achieved.
- the third movement signal can be provided for a third period of time, the third period of time being a multiple of the period duration. This advantageously enables complete revolutions of the drum.
- the method can comprise a step of determining the pendulum frequency using the drum radius value.
- the drum radius value can be read in to a memory unit, for example via an interface.
- the pendulum frequency can be ascertained as a quotient from the root of a quotient of the gravitational constant and the drum radius value and the doubled number of circles. This makes it possible to achieve a pendulum frequency that is adapted to the cleaning device.
- the oscillation frequency can be increased by a predetermined factor in the determination step.
- the predetermined factor can, for example, be in a range between 10% and 40%; the factor is preferably, for example, 20%. This allows the center of gravity of the textiles to be spun to be taken into account.
- the first movement signal, the second movement signal, the further first movement signal and the further second movement signal can bring about a constant acceleration of the drum.
- the control of the rotation can be carried out easily.
- the first movement signal can cause a first acceleration of the drum
- the second movement signal a second acceleration of the drum which is greater than the first acceleration
- the further first movement signal a further first acceleration of the drum which is greater than the second acceleration
- the further second movement signal causes a further second acceleration which is greater than the further first acceleration.
- an ever greater pendulum swing can thereby be made possible so that the textiles nestle evenly against the drum.
- the maximum speed can be reached in the step of repeating in a third repetition process. It is advantageous to swing back three times. As a result, the settling time can be kept short and the textiles can still be taken along safely.
- the approach presented here also creates a control unit which is designed to carry out, control or implement the steps of a variant of a method presented here in corresponding devices.
- the object on which the invention is based can also be achieved quickly and efficiently by means of this embodiment variant of the invention in the form of a device.
- the control unit can be designed to read in input signals and to determine and provide output signals using the input signals.
- An input signal can, for example, represent a sensor signal that can be read in via an input interface of the control unit.
- An output signal can represent a control signal or a data signal that can be provided at an output interface of the control unit.
- the control unit can be designed to determine the output signals using a processing rule implemented in hardware or software.
- the control unit can comprise a logic circuit, an integrated circuit or a software module and, for example, be implemented as a discrete component or be comprised of a discrete component.
- a computer program product or computer program with program code which can be stored on a machine-readable carrier or storage medium such as a semiconductor memory, a hard disk or an optical memory, is also advantageous. If the program product or program is executed on a computer or a control unit, the program product or program can be used to carry out, implement and / or control the steps of the method according to one of the embodiments described above. Furthermore, a cleaning device for cleaning textiles is presented, which has a rotatable, ribless drum for receiving the textiles, a drive for setting the drum in a rotary motion and a control unit in a variant mentioned above.

- step 416 of determining can be carried out before step 402 of providing the first movement signal, as can step 414 of calculating. Steps 414, 416 can also be carried out simultaneously.
- FIG. 5 shows a pendulum curve diagram 500 for a cleaning device according to an exemplary embodiment.
- the speed is shown on the ordinate and the time on the abscissa.
- the pendulum curve diagram 500 can correspond, for example, to the rotational movements of the drum over the time 502, as they were described in the method described in FIG. 4 for carrying out a spin program for a cleaning device.
- the amplitude curve 504 makes it clear that the drum initially oscillates several times and thereby reaches a higher speed value with each oscillating movement.
- the drum movement accelerates, which means that the drum continues to rotate in the current direction and, for example, a spin program of the cleaning device is carried out.
- the direction of rotation of the drum does not change.
- the drum is initially rotated in a first direction for a period of time ti until a rotational speed A (n) Start is reached.
- the time t1 is shorter than or equal to half the period T of the pendulum frequency.
- the drum is then rotated alternately in opposite directions, in each case for a period of half a period T / 2. With each rotation, the speed is increased until the maximum speed is reached, with which the drum can then be used without changing direction a period of time tPI is rotated further.
- the time tPI is greater than a multiple of the period T.
- the drum is rotated in a second direction opposite to the first direction after turning, with a speed of - (A (n) Start + A (n)) will.
- the drum is set in a pendulum movement, that means in a right-left movement, which leads to a pendulum movement of the textiles.
- This has the advantage that an amplitude of this pendulum movement, which is shown here as amplitude curve 504, is gradually increased until it is so great that, by keeping the maximum speed 310 of the pendulum movement constant, the textiles, which are also referred to as laundry, rest securely on the drum shell without falling.
- the pendulum frequency fp endei is to be adapted to the drum radius rr rommei of the drum in accordance with the physical formula of the pendulum frequency.
- a triangular speed curve with increasing amplitude is executed at the corresponding oscillation frequency.
- the triangular shape is achieved by alternately accelerating the drive with constant acceleration in sections, without having to map a sine curve. Since the curve of the angle of rotation represents the integral of the speed curve, the integration properties mean that it is almost sinusoidal, so that the higher frequency components are attenuated by -20 dB / decade. According to this exemplary embodiment, such an approximation is sufficient in practice to safely take the textiles with you without slipping. An exact sine curve is not necessary.
- the triangle curve has the advantage that it can be implemented with a lower computing power of a drive controller, which is referred to here as a control unit.
- a parameterization is advantageously carried out taking into account the previously calculated pendulum frequency. Since this relates to the drum radius, but a focus of the textiles lies further inside, the actual pendulum frequency is approx. 20% higher. Therefore, according to this exemplary embodiment, the period T is increased accordingly by 10 to 40%, preferably 20%, reduced.
- n is the speed, 7r the circular constant (3.1415926535) and g the gravitational constant (9.81 m / s2). Since the radius of the textiles moving on the circular path is smaller than the drum radius, a g-factor greater than 1 is applied. According to this exemplary embodiment, the g-factor is therefore in the range between 2 and 6, preferably 4.
- the corresponding plateau speed npi results, for example.
- a portion of a first half period ki is set in the range between 0.2 and 1 and is preferably 1 in order to realize a suitable phase assignment when transitioning to the plateau speed.
- a starting speed amplitude A (n) sta n and an amplitude increment DA (h) are both set in a range between npi / 10 and npi / 4 and are preferably npi / 4 .
- the maximum speed 310 is 120 1 / min
- the approach described can advantageously be used in washing process technology for cleaning devices with a rib-less drum. It can thereby be ensured that even with a small amount of laundry, the laundry items do not slip when the drum is rotated and are carried along by the drum. This puts the laundry on Spin against the drum shell with sufficient centrifugal force. As a result of the turning process described, it can be avoided that the items of laundry suddenly come into contact only at a higher speed, at which the friction between the drum and the items of laundry is very high. As a result, the formation of an imbalance can be avoided and it can also be avoided that the washing machine vibrates heavily and thereby leaves its set-up position.
